brocade san交换机和ibm刀片上的qlogic san模块级联问题

surain_cu

环境：
brocade 5100：fw 6.3.2,native mode,domain id 1
ibm bladecenter-E上的qlogic 4gb 20port san模块：fw 6.5.0.17,interop 1 mode,domain id 12

原brocade 5100上已有zone信息，把qlogic san模块清除zone信息后再级联，2边端口均为e-port，fabricshow可以看到都在一个fabric了，zone配置也同步到qlogic san模块了；但是，在brocade5100上修改zone配置时，cfgsave报错：RCS is disable，无法保存新配置。

                Bit 10: Administrative Domains(AD) Supported.
                Others: Reserved.

可见qlogic san模块不支持RCS，从而导致brocade5100的zone信息无法同步到qlogic san模块去，zone配置更新就会失败。

据我所知，把qlogic san模块修改为透明模式（类似brocade上的acess gateway模式）是可以和brocade san switch连接正常使用的，这就相当于整个san模块使用NPIV。

我的问题是，大家有没有qlogic san switch和brocade san switch级联成功的case？可以分享下经验么？谢谢。

RCS Disabled when merging with IBM Bladecenter QLogic switches.
Bladecenter QLogic 20-port 4Gb SAN switch module running firmware 6.5.0.17.0
IBM SAN40B switch running firmware 6.4.0c. Not sure exactly which Brocade switch this is OEM'd as.

The SAN40B is running Brocade-native.

Prior to merging set the Qlogic switch to interop_1 mode and verified  the R_A_TOV and E_D_TOV parameters match. Domain ID's are unique. The  switch merged successfully.

Yesterday when I tried to make a zoning change on the SAN40B it failed with:

Zoning transaction aborted Bad Zone Config.
Zoning transaction initiated by user:Admin, Role: Admin could not be completed successfully - RCS is disabled.

and my changes were discarded.

Re-Re-verified with the Qlogic switch interoperability guide my  settings. The switches/fabric seem to be functioning fine. I'm just  unable to make any zoning changes. Been searching for 2-days and just  not finding anything.

Anyone able to help us out..?

Brocade论坛也有人反馈这问题，没人解决。另外QLOGIC和BROCADE是不同的交换机，你这么做两个厂家肯定都和你说不建议，想获得支持都难。建议修改链接模式吧。别级联了。

据我所知Brocade跟Cisco级联的概率还稍微大点，很少看见Brocade跟Qlogic通过E-Port连接的。

楼主为什么不把Qlogic的设置成 Intelligent Path-through模式。
可以参考下IBM的RedBook:

brocade交换机级联是需要Fabric license的，先用licenseshow看下。
另外Qlogic的存储交换机级联好像需要ISL许可。
